The Return of the Harbor Porpoise to San Francisco Bay - Jim Sugar 

Having abandoned San Francisco Bay in the early 1940s, the harbour porpoise have now returned, 65 years later, as a top-level predator and an indicator of the improving health of the bay.   As the film explores, aggressive water health restoration, beginning with the formation of the Save the Bay Foundation in 1963, has allowed for the once dead body of water to again take on life with the return of dolphins, whales, sharks and the famed harbour porpoise.
